Reverse IP Lookup

Reverse IP lookup is the process of checking an IP or a domain name and finding all of the domains hosted at the same IP address on a web server.

What is Reverse IP Lookup?

When choosing a hosting for your website, you may consider shared hosting, which is used by other webmasters who are not related to each other. They have equal rights, and the hosting provider equitably allocates server resources between the websites. This is a standard option for hosting providers that offer shared hosting.

If a web server is configured to serve multiple virtual hosts from a single IP address, multiple websites will be hosted on that IP address. Domains on the same hosting address are called "hosting neighbors".

By using Reverse IP Lookup, a website owner can find out which websites are hosted on the same IP and use the same hosting provider.

Also, you can use this tool to prepare for the relocation of your website or perform the following research:

  • You can determine how many neighbors exist on the same server and whether they might have affected the speed of your website due to server load.
  • Find out which domains share an IP with you and if they might negatively affect your website's reputation and lead to search engine sanctions;
  • Evaluate the integrity of a hosting provider before moving your website. It is common for them to sell more server space than they can afford or to sell shared hosting for the price of dedicated.

What will be the output of the reverse IP check?

You can use this online service if you are unsure whether you have hosting neighbors using the same IP and which websites share hosting with you. It takes the domain name and performs a reverse IP check to identify all the domain names hosted on the web server.

How does the Reverse IP Lookup work?

  1. First, you need to enter the website domain name for which you want to find hosting neighbors and run the check.
  2. The online tool will identify the IP address of a website and show you all matches for that IP address in the database.
  3. This will give you a list of all the domains that have the same IP address as the domain you have checked. In addition, the tool will display a list with the following parameters: IP, Found, Lost, and Domains.

How does the Reverse IP Lookup process work?

The Reverse IP Lookup technique identifies host names with DNS (A) records associated with an IP address. Our online tool can identify which websites share the same IP using Reverse IP Lookup. It uses Google's public DNS to convert it back to an IP address. Then, it will perform an IP lookup through the database to find IP matches,

Why do you need Reverse IP Lookup?

You may need to do a neighborhood search to determine why a search engine has imposed sanctions, to understand why your website loads slowly, to check your hosting provider or to decide which hosting provider to use for your website.

  • Evaluate the reputation of a web hosting

Hosting companies with bad reputations can harm your website and business. Typical problems include deteriorating search engine rankings, failing to deliver emails, and getting your website blacklisted. You can use the Reverse IP lookup service to locate other websites on the same server that may harm your reputation. Later you can use other investigation tools to determine if these websites are not trustworthy: spam or phishing.

  • Learn about exceeding your subscription limit

Shared hosting implies that a hosting provider shares one hosting among several client websites and allocates server resources. To reduce costs, some providers may overuse it, i.e., sell more hosting services than the server can handle. This is often the case with cheaper hosting providers that can host thousands of small websites on a single server. With a Reverse IP lookup, you can determine how many websites you are sharing that host with.

  • Determine the attack surface of the host

In case of an attack on a target host, you need to identify the ports and services used by the target host. Reverse IP lookups can determine hostnames associated with the attacking system. This will find vulnerabilities that can be exploited for hacking. In addition, reverse IP lookups can be used to identify websites on the target host that may contain vulnerabilities. Even if no vulnerabilities are found, disclosure can help understand the target host and how it operates. Identifying additional host names associated with the target can also lead to finding new information, as these hostnames may have additional DNS records pointing to other target hosts.
